Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Objective To investigate the protective effect and underlying mechanisms of HydroMg, a novel sustained-release hydrogen donor, in a model of doxorubicin (DOX)-induced chronic cardiotoxicity. Methods H9C2 cells were treated with 1 μmol/L DOX and/or 1 μg/mL HydroMg, and mitochondrial membrane potential, reactive oxygen species (ROS) levels, and apoptosis were measured. In the animal experiment, mice were divided into control, HydroMg, DOX, and DOX＋HydroMg groups. The HydroMg group received intraperitoneal injection of HydroMg (100 mg/kg). Chronic cardiotoxicity was established by intraperitoneal injection of DOX (5 mg/kg every week) for four consecutive weeks; In the DOX＋HydroMg group, HydroMg (100 mg/kg) was administered intraperitoneally 4–5 h prior to each DOX injection. Cardiac function and remodeling were evaluated by echocardiography and heart weight index (HWI). The long-term survival of mice were analyzed. Subsequently, transcriptome sequencing was performed on myocardial tissues from the DOX group to identify key molecular alterations compared with controls. Results At the cellular level, HydroMg treatment effectively reversed DOX-induced mitochondrial dysfunction and oxidative stress, as evidenced by restored membrane potential, reductions in total ROS and mitochondrial superoxide levels by approximately 30% and 9%, respectively, and a decrease in the apoptosis rate from 34.13% to 18.27%. In the animal model, compared with the DOX group, HydroMg intervention increased left ventricular ejection fraction (LVEF) and fractional shortening (LVFS) by 9.62% and 5.82%, respectively, attenuated the reduction in HWI (4.41 mg/mm vs 3.53 mg/mm), and improved the 4-week survival rate (80% vs 60%). Transcriptomic analysis revealed that the core molecular features of DOX-induced cardiotoxicity, including widespread suppression of oxidative phosphorylation and antioxidant pathways. Conclusions HydroMg protects against DOX-induced chronic cardiotoxicity by alleviating oxidative stress and improving mitochondrial function, and provides a potential therapeutic strategy against DOX-related cardiotoxicity.

Objective:This study aimed to analyze cytomegalovirus (CMV) reactivation and its influencing factors in patients with B-lymphocyte malignancy who received chimeric antigen receptor T (CAR-T) cell therapy.Methods:This study retrospectively reviewed patients with B-lymphocyte malignancy who received CAR-T cell therapy in the First Affiliated Hospital of Soochow University from January 2021 to December 2023. The data of patients who underwent CMV-DNA detection and/or pathogen metagenomic sequencing twice or more within 100 days after CAR-T cell therapy were analyzed. The clinical characteristics of the CMV reactivation and non-activation groups were compared. The factors related to CMV reactivation were analyzed with the Chi-square test and nonparametric rank sum test, and the risk factors were examined with Logistic regression.Results:This study included 86 patients, among whom 18 (20.9%) had CMV reactivation, and the median time of reactivation was 20 (1-95) days. All of the 18 patients had CMV viremia, and no CMV disease was observed. Seven patients turned to the latent state after continuing acyclovir antiviral therapy, and 11 patients returned to the latent state after upgrading the antiviral therapy to first-line drugs, including ganciclovir and foscarnet sodium. Six or more courses of anti-tumor treatment before CAR-T cell therapy, allogeneic hematopoietic stem cell transplantation within 2 years before CAR-T cell therapy, non-remission before treatment, and the use of high-dose glucocorticoids and/or tocilizumab were related to CMV reactivation, among which allogeneic hematopoietic stem cell transplantation within 2 years pre-treatment and the use of high-dose glucocorticoids and/or tocilizumab treatment were independent risk factors for CMV reactivation.Conclusion:Patients with B-lymphocyte malignancy who received CAR-T cell therapy have the risk of CMV reactivation, especially for those who received allogeneic hematopoietic stem cell transplantation within 2 years pre-treatment and those who received high-dose glucocorticoids and/or tocilizumab treatment.

Objective:To evaluate a novel distraction reductor in the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution.Methods:From January 2019 to December 2020, 27 patients with unstable distal radius fracture complicated with metaphyseal volar comminution were treated at Department of Orthopaedics, Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences. They were 6 males and 21 females, with an age of (69.4±9.4) years. All fractures were unilateral and closed, involving the right side in 17 cases and the left side in 10 cases. All patients were treated by internal fixation with an anatomical locking plate through the volar approach and the novel distraction reductor was used to reduce the fracture ends. Regular imaging examinations were performed to evaluate the reduction, maintenance and union of fractures after surgery. One year after operation, the curative efficacy was assessed by evaluation of the range of wrist motion, Disabilities of the Arm, Shoulder and Hand (DASH) score, Gartland-Werley score and Bartra radiology score.Results:All the operations went on successfully with a duration of (92.3±8.9) min. All the incisions healed primarily. The follow-up time was (15.9±2.9) months. The radial height, palmar tilt, ulnar inclination and articular surface step-off immediately after operation [(11.23±1.51) mm, 12.10°±3.44°, 20.54°±3.44°, and (0.95±0.42) mm] were not significantly lost compared with those one year after operation [(11.22±1.55) mm, 12.07°±3.44°, 20.51°±3.33°, and (0.93±0.40) mm] (all P>0.05). One year after operation, the range of wrist motion was good with dorsiflexion of 59.7°±5.5°, palm flexion of 63.0°±9.1°, pronation of 66.5°±5.5°, supination of 61.2°±5.6°, radial deviation of 22.7°±4.8°, and ulnar deviation of 30.3°±6.1°; DASH score was 13.5±5.5; Bartra radiology score was 88.6±6.5, giving an excellent and good rate of 88.9% (24/27);Gartland-Werley score was 2.7±2.1, giving an excellent and good rate of 92.6% (25/27). Follow-ups observed no poor fracture healing, internal fixation failure, tendon or nerve injury or traumatic arthritis. Conclusion:In the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution, the novel distraction reductor can lead to ideal reduction of displaced fractures and effectively correct the shortening caused by volar cortex comminution to achieve satisfactory functional effects in clinic.
